- Everything since March 2026: https://postcutoff.com/since/2026-03/

## What stands out

- Autonomous multi-step web research as an API agent: Runs iterative searching and reading for several minutes and returns a synthesized report; only via the Interactions API with background=true (poll or stream), not generate_content. 'Max' trades speed for comprehensiveness. Source: https://ai.google.dev/gemini-api/docs/deep-research

## Notes

Agent ids, not raw models; the underlying Gemini model and pricing are not stated on the docs page (checked 2026-10-09). The older deep-research-pro-preview-12-2025 was deprecated on 2026-10-08 and shuts down on 2026-10-23 (Gemini API changelog); migrate to deep-research-preview-04-2026 or deep-research-max-preview-04-2026. The '04-2026' suffix suggests an April 2026 snapshot; exact release day not verified.
